maximum number of tablets per tablet server

We have cloudera manager CDH 5.12.1 with kudu 1.4.0 and 1392 tablets per tablet server running, and sometimes we experience "freezing" of kudu/impala, We are wondering if we are not above the maximum number of tables

From cloudera documentation "Recommended maximum number of tablets per tablet server is 1000, post-replication" , however from kudu documentation: "Recommended maximum number of tablets per tablet server is 2000, post-replication." Which one is the correct one?
